Steering shock absorbing structure for in-wheel motor and method thereof

A steering shock absorbing method for an in-wheel motor, the method comprising the steps of:

• detecting, by an acceleration sensor, whether an impact value that is equal to or higher than a preset impact value is applied to the acceleration sensor;
• when the impact value that is equal to or higher than the preset value is applied to the acceleration sensor, determining, by a controller, whether a vehicle is in a driver controllable state;
• in the determining step, when the controller determines the vehicle is in a driver non-controllable state, releasing a tilting braking device;
• detecting, by a tilting angle sensor, whether a tilting unit housing is tilted within a preset tilting limit angle;
• when the tilting unit housing is tilted within the preset tilting limit angle, adjusting, by the controller, a steering angle that is input into a steering input unit and a rotation angle of a steering motor to match each other under a condition that the tilting braking device is released;
• when the adjusting step is completed, detecting, by the tilting angle sensor, whether the tilting unit housing is returned to an original position thereof;
• and
• when the tilting angle sensor detects that the tilting unit housing is restored to the original position thereof, fixing the tilting braking device.
